  • Patent number: 7157736
    Abstract: A multilayer compensator has two or more first layers and one or more second layers. The overall in-plane retardation of the compensator is from 0 to 300 nm and the out-of-plane retardation is more negative than ?20 nm or more positive than +20 nm. The compensator may be fabricated by: coating at least one barrier layer on at least one first layer; coating at least one second layer from an organic coating solvent on the barrier layer to produce an intermediate compensator structure; and stretching the intermediate compensator structure in at least one direction by between 1% and 60%. The barrier layer contains a polymer that is water soluble or water dispersible in an amount sufficient to impede the diffusion of the organic solvent between the other first layers and the second layers. All layers have been stretched simultaneously.

  • Patent number: 7139125
    Abstract: A light redirecting article redirects light toward a target angle. The light redirecting article has an input surface for accepting incident illumination over a range of incident angles and an output surface with a plurality of light redirecting structures, each light redirecting structure having an internal reflection surface oriented at a first angle with respect to the plane of the input surface and an exit surface for emitting an output light at an emitted light angle, wherein the exit surface is oriented at a second angle relative the plane of the input surface. For incident illumination at a principal angle greater than 60 degrees from normal, light is reflected from the internal reflection surface and emitted from the exit surface at an emitted light angle that is within 5 degrees of the target angle.
